Exclude all data from Current Month (in either Beast Mode or ETL)
My aim is to exclude all current month data.
I have tried to do this in ETL, however the date field filter doesn't appear to allow for "less than current month" - happy to take suggestions.
I have also tried in Beast Mode formula. I have successfully excluded data in other calculations using currentdate however am struggling to retain all data except for the current month.
Ideas very welcom, thanks.
